The 12 Pubs of Christmas

Is the 12 pubs of Christmas just an Irish thing or do you do it in different Countries as well? It's one of the only things I look forward to every year.Basically it's just a big pub crawl with you and your mates wearing Christmas jumpers, and you have to get at least 1 drink in each pub

In the spirit of Christmas an open invitation is put out to those who would like to drop out of the Christmas shopping rat race for one day and spend it getting bladdered! making new aquaintances or renewing old friendships lol
